Technical Field

The invention relates to the technical field of building elevators, in particular to a self-locking door structure of a building construction elevator.

Background

With the continuous development and growth of the building industry, land resources become more rare and precious, so that contemporary buildings are developed towards the space direction, more and more high-rise and super high-rise buildings are bred, and the use frequency of building construction elevators is higher and higher. The current safety production is always put on the first place, no safety exists, no benefit exists, no safety exists, no life and property guarantee exists, and the safety production is very important and is the key point of great attention of superior administrative departments; the safety enclosure of the feeding hole of the building construction elevator and the closing of the door of the feeding hole are particularly important. At present, the closing of construction elevator feed inlet door still adopts traditional bolt formula to seal, and its shortcoming is: 1. the bolt type sealing needs manual operation, because of the randomness and laziness of people, the feed inlet door can not be ensured to be always kept in a closed state under the condition of not using, and the open feed inlet door has great potential safety hazard; 2. the bolt type sealing operation wastes time and reduces the construction efficiency. Therefore, in order to guarantee construction safety and improve construction efficiency, innovative research and development are carried out on a construction elevator feeding port door closing lock, so that the door lock can be automatically closed, the feeding port is locked when people go out, and the feeding port is locked when people enter, the situation that the feeding port door is always kept closed when not used is guaranteed, and construction safety is guaranteed.

The invention aims to overcome the defects of the prior art, the door lock can be automatically closed, the feeding port is locked when people go out, and the feeding port is locked when people enter, so that the feeding port door is ensured to be always kept in a closed state when not used, and the construction safety is ensured.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

a self-locking door structure of a building construction elevator comprises a right frame and a left frame which are fixed on two sides of an inlet of the construction elevator, a door frame is arranged between the right frame and the left frame, gaps are arranged between the door frame and the right frame and between the left frame and the door frame, a plurality of hinges are inserted in the gaps between the door frame and the right frame, the door frame and the right frame are hinged through the hinges, a T-shaped support is fixed on the inner side wall of the left frame close to the door frame, a horizontal positioning shaft is inserted and fixed in the support, an obliquely-arranged turnover rod penetrates through the door frame at the left end of the positioning shaft, the turnover rod is inserted and arranged between the left frame and the door frame, the front end of the turnover rod is positioned below the rear end of the turnover rod and is fixed with a horizontal pull rod, an auxiliary rod is fixed at the other end of the pull; a horizontal roller shaft is fixed at the rear end of the turnover rod, a counterweight sleeve is hinged on the roller shaft and is positioned at the rear side of the left frame, a locking groove opposite to the counterweight sleeve is formed in the left frame, and the counterweight sleeve is positioned at the lower side of the locking groove; the upper end face of the turnover rod at the front side of the door frame is pressed against a limiting rod, the limiting rod is fixedly inserted on a connecting rod, and the connecting rod is fixed on a positioning shaft;

and a second permanent magnet block and a first permanent magnet block which are mutually repellent are respectively fixed on the frame of the right frame and the frame of the door frame close to the right frame.

Preferably, the magnetic pole of the front end face of the first permanent magnet block is the same as the magnetic pole of the front end face of the second permanent magnet block.

Preferably, the right frame and the left frame are rectangular frames, and the locking groove on the left frame is a rectangular notch recessed inwards from the frames.

Preferably, the distance from the lower bottom surface of the locking groove on the left frame to the positioning shaft is smaller than the distance from the roller shaft to the positioning shaft, and the width of the locking groove is larger than the diameter of the counterweight sleeve.

Preferably, a plurality of horizontal support rods are fixed between the outer wall of the inner support of the door frame and the inner side wall opposite to the door frame and between the outer wall of the inner support of the door frame and the inner walls at two opposite sides of the door frame.

Preferably, a safety net is fixedly connected to the support rod.

Preferably, the weight of the weight sleeve is larger than that of the pull rod.

Preferably, the distance from the roller shaft to the positioning shaft is greater than the thickness of the left frame.

The invention has the beneficial effects that: the construction elevator door can be automatically closed, the feeding port is locked when people go out, and the feeding port is locked when people enter, so that the feeding port door is always kept in a closed state when not used, and the construction safety is ensured.
